A spokesperson for the Met Office said: "Bands of rain are expected to move eastwards across southwest England during Friday. Rainfall accumulations of 10 to 20 mm are expected over most parts, with 30 mm or more likely over parts of North Cornwall. With the ground saturated over much of the region, the public should be aware of the risk of further local flooding and associated disruption.

"Active frontal troughs will move eastwards across the UK during Friday, a combination of mild, moisture laden air and occasionally strong winds bringing further rain to many places."

It comes ahead of the weekend, when another yellow weather warning has already been issued for Cornwall on Sunday.

That will dump another 2cm of rain on Cornwall - driven on by winds of up to 60mph.
